Dylan Fay wasn't sure what he was getting into.

Greeted by family and friends, he was caught off guard; all smiles at his surprise birthday party.

Life though has been unpredictable for Fay.

The 16-year-old was diagnosed with a rare form of aggressive cancer two years ago. His mother planned this special day for her son.

"It's his last birthday," said Carla Ocampo, Dylan's mom.

"I want to make it special for my boy. Every girl has a sweet 16, you never hear about a boy having a sweet 16, so why not go out with a bang? That's how my son is. He's loud and he's bright."

Fay has synovial sarcoma; a soft tissue cancer which occurs in the bones, muscles or joints. He's spent much of his time being treated at the Hospital for Sick Children in Toronto.

"It's not the most common in paediatrics. We probably see one or two cases a year at Sickkids," said Dr. Paul Nathan, Toronto Hospital for Sick Children.

For Fay, the cancer started in his wrist and it has spread aggressively to his chest.

"The size of toonies," said Fay.

"I got nine of them in my lungs. One of them is in the middle of my lung and it's blocking my lung so it hurts when I swallow and all of that."

An athlete before he was diagnosed, Fay's body won't allow him to play sports the way he once did.

He calls this time of his life scary, but he wants to live it to the fullest.

"I just live day-by-day. Hang out with my buddies and live life, try to live life,” he said.

Fay has stopped chemotherapy; it's no longer effective according to doctors. He started radiation this week at Health Sciences North.

For his Make-A-Wish, Fay and his family went to Vancouver earlier this year and he says he hopes to visit a few more places; especially Chicago and Pittsburgh.

Pittsburgh is the home of his favourite hockey team, the Stanley Cup winning Penguins.
